Hi,
lately I was playing with a new transceiver module that is cheap, small, requires only speaker, microphone, PTT switch, antenna and a battery to run.
Out of the box it runs on 16 preprogrammed channels at the following bands:
CB (27 MHz, 40 MHz, 49 MHz) and UHF (409 MHz up to PMR channels). It's output power is approx. 10 mW.
The module can be seen on this link where you also can find channel frequency chart.
Giuseppe (IK8YFW) has designed 3D enclosure (thanks Giuseppe!), I have printed enclosure with a 3D printer, added wireless charging and a prototype of a simple Walkie Talkie was done.
With added EEPROM one can program different frequencies for 16 channels.
The best news is that this module is cheap:4.50 Euro and it's ideal for entry HAM radio workshops! When presenting it kids just loved it.
